Snow Depth Retrieval Using Chang's Baseline Model (1987) Horizontal or Vertical Polarisation is suitable?

I am currently doing literature review on snow depth retrieval methods using passive remote sensing. While the algorithm in Chang (1987) says it uses brightness temperature difference at 18 and 37...

Does spatial resolution matters while analyzing distribution of CO2 over landcover?

I am analyzing CO2 data over various landcover classes. CO2 data I have obtained from Envisat - SCIAMACAHY (resolution is 0.5x0.5 degree). And the landcover resolution is 0.25x0.25 degree. If we...

How to fill the gaps in satellite data?

I have retrieved CO2 concentrations from EnviSat sciamachy's data sets. But for particular months (June, July, August and September) the data quality is poor. In the sense there were very few...
